Switzer Performance has unveiled their latest Porsche 911 Turbo.

Created for a customer codenamed "AT," the 2007 model has been equipped with Switzer-specific turbochargers, new intercoolers and a high-flow air intake. The car also has a flex-fuel injection system and a stainless steel sports exhaust system.

Thanks to these modifications, the engine develops 900 bhp (671 kW) and more than 800 lb-ft (1083 Nm) of torque. This enables the car to accelerate from 60-130 mph (96-209 km/h) in less than five seconds and run the quarter mile in about nine seconds at roughly 150 mph (241 km/h).

Besides the performance upgrades, the 911 Turbo has been outfitted with H&R lowering springs and 19-inch HRE 597 Rs wheels with Toyo R888 tires.

The mysterious AT plans on entering the car in a number of standing mile events this year and the company says they "expect great things."
